Updated: Oct 28, 2026

Project Cardinal is Pioneer Development’s proposed data center campus in Yorkville, Illinois. City records cover roughly 1,037 acres, a planned-unit development and a campus concept with 14 buildings, including 11 large and three smaller facilities. The tracked 1.8 GW figure is not published as an approved operating or contracted capacity by the city, so Tertiary utility plans, transmission, water, sound controls, building permits, tenants and construction phases remain under review.

Project Cardinal is Pioneer Development’s proposed data center campus in Yorkville, Illinois. City records cover roughly 1,037 acres, a planned-unit development and a campus concept with 14 buildings, including 11 large and three smaller facilities. The tracked 1.8 GW figure is not published as an approved operating or contracted capacity by the city, so the available public sources do not establish a single project-scoped capacity figure. Tertiary utility plans, transmission, water, sound controls, building permits, tenants and construction phases remain under review.
